Handling headset buttons before Voice Search on Jelly Bean

Question

Android Jelly Bean introduced a voice search which activates with a long-press on the play/pause button of a headset. As my app requires being able to utilise these long-presses, I was wondering if there is any way to either disable the voice search or make Android play fair with the button events.

Answer 1

I have not tried it myself, but you may be able to get this to work using the AudioManager's registerMediaButtonEventReceiver method, as the volume buttons are media buttons.

The AOSP music app has a MediaButtonIntentReceiver that responds to volume button presses.
